Performance Evaluation of Hybrid Fiber Reinforced Concrete using Copper Slag as Replacement Material of Fine Aggregate

Concrete is one of the safe, strong and simple building material used in all types of construction works. The main inconvenience in concrete is that the tensile strength is relatively low. The introduction of steel fibers in concrete converts its nature from brittle to ductile. Cracks plays an important role in construction as they change concrete structure into permeable elements and with a high risk of corrosion. It is important to reduce the crack width and this can be achieved by adding polypropylene fibers to concrete. In this experimental investigation, the mechanical properties of HFRC containing Copper slag with various percentages of fibers like Steel fiber and Polypropylene fiber is evaluated. The mixes were designed for five different percentages such as 10 , 20 , 30 , 40 and 50 of Copper slag as replacement of fine aggregate with the small percentage of fibers as constant. The mechanical properties of these mixes were found and then comparing those results with the conventional concrete. The optimum dosage of Copper slag has to be found from these results. By the usage of optimum dosage, structural behaviour and durability characteristics will be evaluated. P. Saranya | V. C.
